Patented July 9, 1935 UNITsDsr T s PATENT OFFICE My present invention relates to garment press- I ing machines and'has particular reference to means for facilitating the drying of the garments or fabrics which have beenpressedthereon.

In the usual type of garment pressing machines comprising a pair of relatively movable pressing elements, such as the usual head and buck, there has been provided suction apparatus for drawing air through the garments after they have been steamed and pressed. However, the garment pressing machines made prior to my invention and which were equipped with suction apparatus for drawing air through the garmentsrequire that the head be raised before the air can be drawn through the. garment to remove excess moisture therefrom. A serious objection to drawing the air through the garments after the head has been raised is tha-tithe air is drawn down at room or atmospheric temperatures against and through the hot and moistgarment, so that the steam orhot vapor in the garment whencontacted by the cool air condenses and the garment is not as effectively dried as is possible with appa ratus embodying my invention,"which provides for drawing preheated air through the garment while the pressing elements are still in pressing relation, and, therefore, without exposing the garment toatmospheric or room temperatures.

Means by which I accomplish the foregoingare illustrated'in the accompanying drawings, it .being understood that the drawings disclose preferred illustrative embodiments of the invention, and that variations in the construction and arrangement of the parts for accomplishing the above specified purpose may be made, as hereinafter pointed out. I

In the drawings,

Fig. 1 is a longitudinal central sectional view through the head of a pressing machine showing a front elevation of portions of the buck and the steaming valve;

Fig. 2 is a View similar to Fig. 1 showing a portion of the buck broken away and showing a conventional suction apparatus applied to the buck;

Fig. 3 is an enlarged fragmentary sectional view of a fragment of the head and buck showing a modification in mechanism'embodying my inventioniapplied to the head; Fig. 4 is a fragmentary sectional view of the pressing head with another modification of my invention applied thereto; and

Fig.5 is a View similar to Fig. 3 showing a further modification.

"In the drawings, the letter H designates generally the pressing head which has a chamber 5 formed between the top plate 6 and intermediate plate '5, into which steam is admitted through an inlet 3 from any suitable source of supply. A valve body 9 is screw threaded into the intermediate plate "I andextends through the top plate 6 against which it is tightly sealed by any suitable means. A. passage") in the valve communicates with the chamber 5, and another passage I l communicates with the spray chamber l2 which is formed between the plate 1 and the perforated plate l3 forming the lower face of the head. The valve M is provided with a seat 14a at the top of the passage in for the disc l4 carriedby a stem 65 which is connected to lever l6 pivoted onuprights I! on top of the valve. Communication between the passages Ill and 'Il may be established to permit steam to flow from the chamber 5 to the chamber l2 and through the perforations of the plate 13 in usual manner when pressing by operating lever [E3 to raise disc I l.

The buck is designated generally by the ,letter B and it includes a top perforated plate [8 and a bafiie plate 19 providing a chamber 26 into which the steam is projected when the valve head I4 is raised from the seat 13 in known and usual manner. I have also shown in Fig. 2 a known type of suction apparatus, such as shown in Patent 1,193,093, including a pipe}! which communicates with chamber 20 and also with a fan ZZ which has an outlet 23. Inthe pipe 26 between the fan '22 and'the buck is a valve 24 controlled by rod '25- connected to a bell crank 26 which is pivoted on a bracket 27; supported by'the buck; Another'rod 23 is corrto be described may bev used in connection with various types of heads and exhausting or suction apparatus. It, is with apparatus of the type shown and described and similar machines that the garments or fabrics" F between the head and buck are steamed and pressed when-the head is clamped down against the buck either by the usual treadle operated levers or pewer mechanism not shown, and after which the'head must be raised from the fabric before the suction apparatus can function. Obviously, when the pedal 29 isdepressed the bell crank 26 will be rocked andthe valve 24 opened, so that air may be sucked through the fabric or garment and buck through the perforationsin the plate "I3 and chamber 20. With the head elevated, this airis at atmospheric or room temperature and results in the condensation above mentioned.

To more effectively and quickly dry the garments, I provide for drawing the air through the head while it is in pressing relation with the buck and fabrics or garments therebetween, and while so doing heating the air to avoid the condensation which results from drawing air at atmospheric or room temperatures through garments or fabrics with the head raised.

In Figs. 1 and 2, I have shown a tubular passage 30 at each side of the valve 9 formed through the head between the plates 6 and! and communicating at their lower ends with the chambers l2. On top of the plate 6 above the passages 30 there are bosses 3| screw threaded on their interiors to receive the lower screw threaded ends 32 of valves designated generally by the numeral 33. These valves have on their interior ribs or webs 34 provided with lugs 35 on their lower ends. A disc 36 is loosely mounted in the valve and normally rests on the lugs 35 spaced from the shoulder 31 on the interior of the valve beneath the port 38. Since the walls of the passages 30 extend through the steam receiving chamber 5, they are heated so long as the chamber 5 is supplied with steam, that is, when the apparatus is in use.

I wish it to be understood that while I have shown two of the valves 33 located at corresponding points on the head, that I may provide only one of such valves or more than two and locate them at any point orpoints on the head which I may select.

In Fig. 1, the steam valve is shown open and the arrows indicate the passage of the steam into the chamber 5 from the inlet 8 through the passage l0 and down through passage H into chamber l2, and thence through the openings in theperfor'ated plate [3 to steam the garment or fabric while it is being pressed. In this open position of the steam valve, the air valves 33 are automatically closed by the steam pressure as indicated by the arrows showing the steam entering the passages 30 and consequently lifting the discs 36 into engagement with the shoulders 31 and closing the ports 38. However, as shown in Fig. 2, when the steam valve is closed the pressure on the discs 36 is released and they gravitate down onto the lugs 35 in the port 38, so that air may fiow through the ports around the discs in the spaces between the ribs 34 and down through the passages 30 into the chamber I2. This flow of the air is facilitated by operation of the suction apparatus, for obviously, when the valve 24 is opened in the manner previously described, the air is sucked through the passages 30 and chambers l2 and 20 in considerable volume, while at the same time being heated by contact with the heated walls of the passages 30 and the heated plates 1 and 13 of the head.

In actualpractice, I find that garments and fabrics when subjected to the drying action provided by my invention, are far more completely and quickly dried than when air at atmospheric or room temperatures is passed through them with the head raised.

To facilitate or increase the heating of the air which is drawn through the garments in the manner bove explained, I may provide, as shown in Fig. 3, in connection withthe apparatus such as shown and described in Figs. 1 and 2, a bafiie plate 40 immediately beneath each of the passages 30 or either one of them and spaced from the heated plate 1. The distance which the battle plates 40 are spaced from the plate 1 may be determined by spacer blocks 3| through which and the plates 40 extend screws 42 which engage into the plate 1 to hold the baflle plates 40 in place. The plates 40, as well as the plate I, will be heated, and due to the restricted area therebetween, the air will be additionally heated as it enters the chamber.

While I have shown in Figs. 1-3 a gravity actuated valve vertically mounted on top of the head, it is possible to provide a horizontal hinged valve to admit air through the side of the head, as shown in Fig. 4, wherein .a valve casing 43 is screw threaded into the side wall 44 of the head in alinement with a passage 45 which communicates with the chamber 12 corresponding to the chamber l2. The valve casing 43 is provided with an internal shoulder 43 against which the valve 41 is forced to close the passage 45 or its communication with the atmosphere when the steam is being sprayed as previously described, the valve 41 being pivotally mounted at 48 in the top of the valve casing. When the suction is applied, the valve 41 swings to open position on its pivot 48 admitting the air. Also if desired, a baflie plate similar to the bafile plate 40 in Fig. 3, may be mounted beneath the passage 45 to increase the heating of the air as it enters. There may be as many valves 43 as desired on each head.

In Fig. 5, I have shown an arrangement generally similar to the air valves of Figs. 1-3, except that a plate 50 closes the top of the valve and provides a space 5| above the top of the head through which air is drawn and preheated. The air then passes through openings 52 and between the ribs which support the disc as in the other embodiments of the invention.

I do not wish to limit the invention to the specific construction and arrangement of valves shown and described nor the exact manner in which they are connected to the head, and of course the invention may be practiced in connection with various types of pressing machines whether manually or power operated. I also wish to point out that it is not absolutely necessary to the practice of the invention to have the steam spraying valve on the head alone as there may be a steam spraying valve on both the head and buck either of which may be used.

I claim:
